INORA-a unified signaling and routing mechanism for QoS support in mobile ad hoc networks

Mobile ad hoc networks (MANET) are characterized by bandwidth constrained wireless links, multiple hops and highly dynamic topologies. Providing QoS support in MANETs is hence a challenging task. This paper presents the design, implementation and evaluation of INORA, which is a network layer QoS support mechanism that makes use of the INSIGNIA in-band signaling mechanism and TORA routing protocol for MANETs. TORA provides multiple routes between a given source and destination. We present an effective coupling between TORA and INSIGNIA to get routes that are "best-able" to provide QoS requirements for a flow. INORA also combines congestion control with routing.
